Function msg

pub fn msg(message: impl Display) -> ExpectedField

Construct a new message ExpectedField.

For details on how to set the value of the message field and how to expect multiple fields, see the field module and the ExpectedField and ExpectedFields structs.

This is equivalent to expect::field("message").with_value(message).

Examples

use tracing_mock::{collector, expect};

let event = expect::event().with_fields(
    expect::msg("message"));

let (collector, handle) = collector::mock()
    .event(event)
    .run_with_handle();

tracing::collect::with_default(collector, || {
    tracing::info!("message");
});

handle.assert_finished();

A different message value will cause the test to fail:

use tracing_mock::{collector, expect};

let event = expect::event().with_fields(
    expect::msg("message"));

let (collector, handle) = collector::mock()
    .event(event)
    .run_with_handle();

tracing::collect::with_default(collector, || {
    tracing::info!("different message");
});

handle.assert_finished();
